FOR THIS EVENING, AN AREA OF THUNDERSTORMS IS EXPECTED TO APPROACH
FROM THE EAST. THESE STORMS WILL EVENTUALLY WEAKEN. HOWEVER,
UNCERTAINTY EXISTS REGARDING WHEN THE WEAKENING OF THESE STORMS

THUNDERSTORMS IN THE VICINITY OF GALVESTON AND GALVESTON BAY THIS
EVENING IF THE STORMS DO NOT WEAKEN IN TIME. OTHERWISE, LIGHT TO
OCCASIONALLY MODERATE EAST TO SOUTHEAST WINDS AND 2 TO 4 FOOT SEAS
SHOULD CONTINUE OVER THE NEXT SEVERAL DAYS ALONG WITH A DAILY
RISK OF ISOLATED TO WIDELY SCATTERED SHOWERS AND THUNDERSTORMS. AS
SURFACE HIGH PRESSURE MOVES A BIT FURTHER EAST, A MORE PREVALENT

WEEKEND INTO EARLY NEXT WEEK.
